I enjoy taking group pictures and simply anything related to the lab. Here, you will see some of the pictures I took while working at Penn State and MIT.

    The Chemistry Behind TRAB

    A copper salt was used in both chambers of TRAB, and additional ammonia was added to the anolyte.

    My Adviser, Prof. Logan, and I

    Such a great honor to work with Prof. Bruce Logan during my Ph.D. program at Penn State University.

    TRB Reactor

    This is a simple “cube” type TRB reactor, consisting of blocks of polycarbonate drilled to have a 3cm diameter chamber. The two chambers are separated by an anion exchange membrane. The copper electrodes are inserted through one of the stoppers used to seal the reactor (two holes are used to drain and re-fill the reactor).

    Thermal Regenerative Battery (TRB)

    Two TRB reactors showing the reference electrodes in each chamber that are used to measure the Cathode and anode potentials.

    TRB Configuration with Bottles

    A different type of TRB reactor configuration made using two bottles (each 80 mL) and a membrane clamped between the side arms.

    TRB Reactors in Operation

    TRB reactors in operation, where the catholyte is stirred using a stir bar and stir plate, to reduce mass transfer limitations for ion transport to the cathode.
